Question

solve this two question I will mark as Brainliest it's urgent​

Answer 1

Answer:

1) 3

Step-by-step explanation:

(7/12)^-4 * (7/12)^3x = 7/12^5

[a^m * a^n = a^m+n]

(7/12)^-4 * (7/12)^3x = 7/12^5

= -4 + 3x = 5

3x = 5+4

3x = 9

x = 9/3

x = 3

Answer 2

Step-by-step explanation:

1.

we know that if there is multiplication of numbers having power with same base ... then power is added

thus

(7/12)^(-4+3x) = (7/12)^⁵

on comparison

-4 + 3x = 5

3x = 9

x = 3

2.

let x be multiplied to the given number

thus

x * (3/2 )^2 = (-4/5)

x = -4/5 * 4/9

x = -16/45
